If Florida ends school vaccine mandates, hundreds will die within five years
A mathematical model shows that eliminating Florida's required school vaccinations would trigger the nation's worst measles outbreak in nearly five decades, potentially killing hundreds of children and infants within five years.

Pro-vaccine officials can't stay at the CDC
Jennifer Shuford, the CDC's deputy director, is a data-driven epidemiologist who understands the critical importance of childhood vaccination. She took office in June this year and her tenure ended on November 12. Her departure coincides with the CDC facing criticism over its response to the measles outbreak. The host suggests that her support for vaccination put her at odds with administration priorities, preventing her from having impact—another instance of key talent loss at the agency when public health should transcend politics.

H5N1 sequences from Utah's mink farm outbreak are related to the B3.13 genotype circulating in Texas cattle and already carry the PB2-M61L mutation that enhances mammalian replication. Like pigs, mink have respiratory tracts rich in α2-6 sialic acid receptors—the same ones found in human upper airways—making them ideal hosts for viral adaptation to mammals and potential genetic reassortment. The Netherlands culled all its mink farms during the pandemic; the host believes the U.S. should do the same, but that's unlikely under the current administration.
Florida's dengue outbreak has no approved vaccine
After three counties declared a state of emergency over ‘exceptionally unusual’ dengue cases, Florida's case count surged from 392 in September to 721. Experts attribute this to climate change expanding mosquito populations and lengthening the active season—an inevitable outcome—yet the U.S. has no approved dengue vaccine on the market. Genuine local transmission has already occurred, and children face especially high risk. Social media is filled with frustration over Florida's public health policies.
This Ebola outbreak is approaching record deadliness
The epidemic curve continues to rise with no plateau in sight. Cumulative cases have exceeded 10,000, and deaths are approaching 5,000 (updated data as of writing showed approximately 5,000 deaths). It is rapidly becoming the deadliest Ebola outbreak in history. The host complains that international aid efforts are obstructed—some third countries impose 21-day quarantine requirements on aid workers, deterring those wanting to help. Index cases from Kenya and Nigeria both passed through Entebbe Airport in Uganda, suggesting it may be a transmission hub.
— Daniel GriffinEnding school vaccine mandates will kill hundreds of children
A mathematical model based on a PNAS paper shows that if Florida eliminates mandatory school vaccination requirements, it could trigger the nation's largest measles outbreak in nearly half a century, with hundreds of child and infant deaths possible within five years. The host is blunt: this is what voters are deciding with their ballots—whether to accept hundreds of children dying. Public health ranks near the bottom of voters' priorities.

A retrospective cohort study from Spain involving approximately 280,000 adults over 80 found that compared to standard-dose vaccine, high-dose flu vaccine reduced hospitalization risk by 34% and showed 42% greater protection against laboratory-confirmed influenza. Surprisingly, there were cardiovascular benefits: relative effectiveness in preventing heart attacks was 26.4%, stroke 32.9%, and pulmonary embolism 27%—these are additional gains on top of the protection already provided by standard-dose vaccine.
Severe COVID has nothing to do with your genes
A Danish registry study involving 83,902 twin pairs and 37,719 spouses found no evidence that genes influence COVID severity. Hospitalized twins' spouses were not at higher risk of hospitalization as would be expected if genetics mattered. Instead, unrelated spouses (the control group) showed significantly higher hospital admission concordance across all epidemic waves—hospitalized patients' spouses had a relative hospitalization risk of 3.56. The host expressed surprise at ‘zero genetic influence’, though he questioned whether Denmark's homogeneous population makes the conclusion less generalizable to other countries.
— Daniel GriffinNo one knows whether to give the fifth rabies shot
A nurse's patient developed a rash while receiving rabies vaccination because of a prescribed prednisone dose, and whether to give the fifth shot became a question no one could answer: the county rabies service didn't know, the hospital's infection control couldn't consult, the CDC Atlanta office took a week to call back and then referred the question to the state health department. Finally, the emergency room made the call to complete the fifth dose. Daniel explained that prednisone is immunosuppressive and should be treated according to guidelines for this population—the patient should receive the full series and have antibody titers checked three weeks later to confirm protection.

Both pigs and mink have a high proportion of sialic acids with alpha 2-6 linkages, similar to those found in the human upper respiratory tract
there is currently no licensed dengue vaccine available in the US
this is very quickly turning into the worst Ebola outbreak in history.

this is what you're voting for. You are voting on whether you agree with hundreds of young children dying over the next 5 years, because that is where we are headed.
Daniel Griffin24:29
the high dose was associated with a lower risk of hospitalization, 34% lower.
I am very surprised that there is no genetic influence on the severity of the disease.
Daniel Griffin45:52
I contacted the district rabies service, where they told me they didn't know.

Glossary
- clade 2.3.4.4B
- The H5N1 bird flu lineage currently circulating globally, having infected cattle and multiple mammal species

How to listen
People concerned with how U.S. vaccine policy affects child health, and clinical or public health professionals wanting to understand the real-world effectiveness differences between high-dose, mRNA, and Novavax flu vaccines.
